Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There are security vulnerabilities in the Linux kernel. These vulnerabilities stem from the fact that ksmbd does not verify the SID length of inherited ACEs in the...

PT-2026-41267

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the ksmbd module, the smb inherit dacl function fails to verify that the variable-length Security Identifier SID described by sid.num subauth is fully contained within the Access...

CVE-2026-44699: Use of a Broken or Risky Cryptographic Algorithm

LibJWT is a C JSON Web Token Library. From 3.0.0 to 3.3.2, libjwt accepts an RSA JWK that does not contain an alg parameter as the verification key for an HS256/HS384/HS512 token. In the OpenSSL backend, this causes HMAC verification to run with a zero-length key, so an attacker can forge a valid...

Linux Distros Unpatched Vulnerability : CVE-2026-43490

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ksmbd: validate inherited ACE SID length smbinheritdacl walks the parent directory DACL loaded from the security descriptor xattr. It verifies that each ACE...

GHSA-9RMH-MM8F-R9H6 Svelte: ReDoS in `<svelte:element>` Tag Validation

An internal regex in the Svelte runtime can take exponential time to test in . You are only vulnerable to this if you allow tags of unconstrained length. If your application only allows a predetermined list of tags or trims their length before passing them to svelte:element, you are safe...

DEBIAN-CVE-2026-43903

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, sgiinput.cpp:265,274 use OIIODASSERT for bounds checking in the RLE decode loop. In release builds, OIIODASSERT compiles to voidsizeofx...

CVE-2026-44523

Note Mark is an open-source note-taking application. Prior to 0.19.4, no minimum length or entropy is enforced on the JWTSECRET configuration value. The application accepts any base64-decodable secret regardless of size, including secrets as short as 1 byte. This vulnerability is fixed in 0.19.4...

CVE-2026-43904

OpenImageIO prior to 3.0.18.0 and 3.1.13.0 has a heap overflow in the RLE decoder for the Softimage PIC path (softimageinput.cpp:469 and :345) because run length is not clamped to scanline width before writing pixels. The raw packet path clamps correctly, but the RLE paths do not, allowing a craf...
